Procedure 6: Renaming the Managed SYSnn
(Optional)
1. Check that you are in the target system ZDSMSCM subvolume.
2. Review the detailed list of every file that ZPHIRNM will rename.
3. Run ZPHIRNM in PREVIEW mode:
> RUN ZPHIRNM [$ vol .]SYS nn , PREVIEW [STRICT] [, option ]...
4. If the process generates errors, correct them and run ZPHIRNM in PREVIEW
mode again. When no errors remain, continue.
5. Run ZPHIRNM with the appropriate extensions (without PREVIEW).
If you did not specify a log file, a prompt asks whether to use a log file.
6. Enter Y; then press Enter.
A prompt requests a log file name.
7. Enter a disk file name.
A prompt indicates the log file was created. ZPHIRNM issues an EMS message
when it has successfully completed.
Procedure 6: Renaming the Managed SYSnn
(Optional)
After you configure an update on a different SYS nn , you can rename that SYS nn to
the one from which you always want to load your system. For example, to always load
your system from SYS00, configure your update on SYS01; then rename SYS01 to
SYS00:
1. Perform an Apply on the new SYS nn (in this example, SYS01).
2. Run ZPHIRNM on the new SYS nn (SYS01).
3. Rename the running SYS nn (SYS00) to another unused SYS nn (SYS20).
4. Rename the running CSS nn (CSS00) to another unused CSS nn (CSS20).
5. Rename the new SYS nn (SYS01) applied by DSM/SCM to your usual SYS nn
(SYS00).
6. Rename the new CSS nn (CSS01) applied by DSM/SCM to your usual CSS nn
(CSS00).
7. Perform a system load on your usual SYS nn (SYS00), which now contains the
updated software configuration.
8. Restart DSM/SCM.
9. Update the DSM/SCM database with the new SYS nn s. (You do not have to do this
immediately, but do it as soon as possible in case you need to back out to the
previous revision.)
